The chart above shows the number of people enrolled in the ACA’s insurance marketplaces or covered through its Medicaid expansion.
These options have become especially important over the last six months, as millions of Americans lost their jobs — and thus their employer insurance — due to the pandemic.
And more than a quarter of non-elderly Americans have a pre-existing condition that insurers in the individual market could refuse to cover without the ACA, per the Kaiser Family Foundation.
The big picture: Republicans paid a steep electoral price for trying to repeal parts of the ACA in 2017. Republicans’ lawsuit against the health care law, if it succeeds, would boot even more people off of their coverage and undo even more of the ACA’s regulations.
